. Specification forming part of Letters Patent No. 195,399, datedSeptember 18, 1877; application filed April 17, 1877.

To an whom it may "concern:

Be it known that 1, WILLIAM QUAYLE, of Peoria, in the county of Peoriaand State of Illinois, have invented a new and useful Improve'ment inChimney-Tops and Ventilators, which i mprovenien'ti-s fully set forth inthe following specification and accompanying drawings.

My object is to produce a cap for chimneys and ventilating-Hues,"adapted as an ejector for smoke and gases and exclude rain, being alsoadapted as a ventilator for air-shafts for buildings, 8m, theconstruction being such as to allow an efl'ective draft, whether thewind be blowing horizontally, upward, or downward.

In accomplishing this I find that the flueoutlets should be equal inarea to the flue of the chimney, and for this purpose the centralcap-deflector is arranged in such relation to the top of the chimney andto a surrounding outside vertical flue as to make the area of the outletbeneath the cap-deflector and of the vertical side flue each equal tothe area of the chimney-flue, and by this means prevent the leastimpediment in the draft of the chimney.

Many chimney caps have been designed with central deflectors and outsideflues; but so far as I know there has been no provision for equalizingthe outlets with the chimneyflue, which is vital to a proper draft ofthe chimney.

The cap is telescoped with the chimney and supported upon the topthereof by an inwardly-bent flange formed upon the upper edge of thetelescoping portion, and this part serves to bind the bricks in placeand protect them from the effects of the weather. The lower edge of thetelescoping portion of the cap is formed into a gutter-shaped moldingwith open corners, whereby the rain or drippings from the deflector andfrom the outer chimney-wall are collected and pass out at the opencorners of the spout, and thereby prevent any discoloration of thechimney-wall from this cause.

The outside vertical flue is formed by the 'outer cap portion or case,which is secured to the inner telescoping portion by quoin-brackets atpoints below the chimney-top. The capdeflector is supported by angle-irons, which fit over the angles on the outside of the telescopingportion, and the angles on the inner side of the outer case.

The vertical flue is formed by the outer case outside of thechimney-wall, and is open below the chimney-top and above thecap-deflector, the outer case beingcurved inward above the deflector tobring the top outlet in line with the vertical sides of said deflectorand the chimney-wall, so that the wind may blow downward or upward, butis prevented from being blown down the chimney-flue.

In the claims I shall specifically point out the particular features ofmy improvement.

Referring to the drawings, Figure 1 represents an elevation of a chimneycap and ventilator embracing my invention; Fig. 2, avertical sectionthereof, and Fig. 3 a horizontal section, taken above the chimney-flue.

The cap consists of a wall portion, A, which telescopes a suitabledistance with the upper portion of the chimney, and an outer case orshield, B, which incloses the central cap-deflector O, and forms avertical flue, D, outside of the chimney-wall and above the chimney.These two parts A and B are secured together by quoin-brackets E belowthe chimney-top, and the central cap-deflector is secured in positionover the chimney-flue by angle-irons F, secured to and extending fromthe angles of the wall portion A, on the outside, and to the angles ofthe shield-case B, at the inner side of the top thereof. The parts thussecured form the cap, which is secured and supported by means of aninwardly-bent flange, a, at the upper edge of the wall part A upon thechimney-top, as shown in Figs. 2 and 3.

The central cap-deflector extends over and above the chimney-flue, so asto bring its sides in line with the wall part A, thus forming ahorizontal outlet, b, between the central cap and the top of thechimney, while the outer case B extends from a point below thechimney-top to above the cap-deflector, forming a surrounding outsideflue, 0, the top outlet 01 of which is in vertical line with thevertical sides of the deflector, and is formed by an inward and upwardbend, e, of the outer case, so that the smoke and gases from the chimneypass out beneath the cap-deflector and are driven up or down the sideflue according as the wind may be blowing. In either case the draft andsuction of the side flue will always preserve the upward draft of thechimney. This result, however, is only efl'ectnally obtained by reasonof the equalization of the outlets and the chimney-flue. At three pointsof outletviz., b c d-this equalization of area must be made with thechimney-flue in order that the draft may be as free at the outlets aswithin the chimney.

The wall part A terminates atitsloweredge in a gutter, G, which is open,as at f, at the angles of the chimney, so that the rain and drippingsover the wall portion are collected in the gutter and pass ofl' at thecorners away from the wall, and prevent the chimney-wall from beingdiscolored from soot, &c.

The top of the cap-deflector is made conical to shed the rain. Theshield or case B rises from the curved part a so as to bring the top Bin line with the vertical sides of the deflector and chimney-wall, andbring the opening most prominent of which is a shelf-like molding andlarge ovolo at the top portion.

I claim- 1. The cap-deflector C, and the outer case B, constructed andarranged with reference to the outer wall of the chimney and its flue,to form the vertical side flues c D, the cap-outlets d, and the mainflue outlets b, of equal area with the chimney-flue, said outlets b dbeing in line with the outside of the chimneywall, as shown anddescribed.

2. The telescoping part A, having the inward-bent flange a, incombination with the quoin-brackets E, and the angle-irons F, as and forthe purpose herein set forth.

3. The combination, with the wall part A of a chimney-cap, of the gutterG, having the open ends f, as and for the purpose herein set forth.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.

WILLIAM QUAYLE.
